no longer obstructs the inner diameter of the focus barrel.
Remove the protective dust cap from the focuser barrel.
2.
Slide the chrome portion of the star diagonal into the eye-
piece adapter.
3.
Tighten the thumbscrew on the eyepiece adapter to hold
the star diagonal in place.
If you wish to change the orientation of the star diagonal,
loosen the thumbscrew on the eyepiece adapter until the star
diagonal rotates freely. Failure to do so will result in unthread-
ing the chrome barrel from the diagonal housing. Rotate the
diagonal to the desired position and tighten the thumbscrew.
the Eyepiece
The eyepiece, or ocular, is the optical element that magnifies
the image focused by the telescope. The eyepiece fits either
directly into the focuser (114mm and 130mm models) or into
the star diagonal (80mm model). To install the eyepiece:
For StarSeeker 80mm model:
1.
Loosen the thumbscrew on the star diagonal so it does
not obstruct the inner diameter of the eyepiece end of the
diagonal. Remove the protective dust cap from the star
diagonal's barrel.
2.
Slide the chrome barrel of the low power 25mm eyepiece
into the star diagonal.
3.
Tighten the thumbscrew to hold the eyepiece in place.
To remove the eyepiece, loosen the thumbscrew on the star
diagonal and slide the eyepiece out.
For StarSeeker 114mm and 130mm models:
1.
Loosen the thumb screw on the eyepiece adapter at the
end of the focuser barrel and remove the protective dust
cap from the focuser barrel.
2.
Slide the chrome barrel of the low power 25mm eyepiece
into the eyepiece adapter.
3.
Tighten the thumbscrew to hold the eyepiece in place.

Eyepieces are commonly referred to by their focal length and
barrel diameter. The focal length of each eyepiece is typically
printed on the eyepiece body. For example this telescope ships
with two 1.25" diameter eyepieces; a 25mm and a 10mm. The
longer the focal length (i.e., the larger the number), the lower
the eyepiece power or magnification; and the shorter the focal
length (i.e., the smaller the number), the higher the magnifi-
cation. Generally, you will use low-to-moderate power when
viewing. For more information on how to determine power,
see the section on "Calculating Magnification."
Barrel diameter is the diameter of the barrel that slides into
the star diagonal or focuser. The StarSeeker uses eyepieces
with a standard 1.25" barrel diameter.
Focusing
To focus your telescope, simply turn either of the focus knobs
at the eyepiece end of the optical tube (see Figures 6 and 7).
Turn the focus knob until the image is sharp. Extending the
focus tube brings objects closer to you in focus. Conversely,
for distant objects draw the focus tube inward.
installing the EZ Finder ii
StarSeeker 80
Slide the base of the EZ Finder II (2) bracket into the dovetail
holder that is molded into the focuser body on the optical tube
(3). The EZ Finder II should be oriented so that it appears as
in Figure 1. Tighten the thumbscrew on the dovetail holder to
secure the EZ Finder II in place.
StarSeeker 114
Remove the two metal thumbscrews from the optical tube
(Figure 3). Place the bracket of the EZ Finder II (2) on the
tube so that the holes in the bracket slide over the two thread-
ed posts on the tube. The EZ Finder should be oriented so
that it appears as in Figure 1. Thread the thumbscrews back
onto the posts to secure the EZ Finder II in place.
StarSeeker130
Slide the base of the EZ Finder II (2) bracket into the dovetail
holder (Figure 4) that is pre-installed on the optical tube (3).
The EZ Finder II should be oriented so that it appears as in
